On Russian calendars the days of the week are placed on
the left side, not on the top row.
The Russian week begins on
Monday. Look at the example:

To answer the question когда? with days of the week, we use the preposition в and the day of the week in the
accusative case:
В среду мы были дома. On Wednesday we were at home.
В четверг мы смотрели телевизор. On Thursday we watched television.
The names of the days of the week are not capitalized in Russian.
